Verified Answer
In humans, visceral organs are innervated by[1996]a)sympathetic nerves...
The activities of all visceral organs are coordinated through the regulation of their smooth muscles and glands by the nerve fibres of the sympathetic and parasympathetic nervous system. These constitute the autonomic nervous system which carry out functions that are not under the control of our will.

Answer:
In humans, visceral organs are innervated by both sympathetic and parasympathetic nerves, but they are not under conscious control. The correct answer is option D.
Explanation:
Sympathetic Nerves:
- The sympathetic nervous system is responsible for the "fight or flight" response, which prepares the body for intense physical activity or emergency situations.
- Sympathetic nerves originate from the thoracic and lumbar regions of the spinal cord.
- They innervate the visceral organs, including the heart, lungs, liver, stomach, and intestines.
- Sympathetic stimulation increases heart rate, dilates the bronchioles, constricts blood vessels, and slows down digestion.
Parasympathetic Nerves:
- The parasympathetic nervous system is responsible for the "rest and digest" response, which conserves energy and promotes relaxation.
- Parasympathetic nerves originate from the cranial and sacral regions of the spinal cord.
- They also innervate the same visceral organs as the sympathetic nerves.
- Parasympathetic stimulation slows down heart rate, constricts the bronchioles, dilates blood vessels, and enhances digestion.
Not under Conscious Control:
- The autonomic nervous system, which includes both the sympathetic and parasympathetic divisions, controls involuntary functions of the body.
- These functions, such as heart rate, digestion, and breathing, are regulated automatically and are not consciously controlled.
- For example, we do not have conscious control over our heart rate or the secretion of digestive enzymes.
- The autonomic nervous system operates unconsciously and is regulated by various factors, including internal and external stimuli.
Therefore, visceral organs in humans are innervated by both sympathetic and parasympathetic nerves but are not under conscious control.
